What research shows
Snakes appear in dreams far more often than exposure to real snakes would predict, which has been used to argue for an evolved threat-detection response.

Dreaming about snakes
Threat, transformation, or something hidden in the grass.
The psychological reading
Freud read the snake as sexual; Jung read it as transformation and the unconscious. In practice the emotional tone of the dream decides — a frightening snake and a calm one are not the same symbol.
What tradition claimed
A near-universal omen of betrayal by someone close, though in parts of Asia it signals wealth.
Included as cultural history. Traditional dream books are frequently ominous and have no predictive value.

Over-represented relative to real-world exposure. Reported at similar rates in countries with and without venomous snakes.

Figures come from the Typical Dreams Questionnaire, the standard instrument in dream research since 1958. Dream dictionaries almost never cite a number for how common a dream actually is — the research exists, it just does not get quoted.
The version matters
Different ways this dream shows up
Most dream dictionaries give one meaning for the whole symbol. In practice the specific version carries most of the information — losing every tooth and losing one tooth are not the same dream.
A snake biting you
Usually the most frightening version, and often tied to a specific betrayal or a health worry.
A snake in the house
Domestic — something unwelcome inside a space that should be safe.
Many snakes
Overwhelm rather than a single threat.
A calm or friendly snake
Reads entirely differently: transformation and healing rather than danger. The medical caduceus is a snake for this reason.
Killing a snake
Traditionally a victory over an enemy; psychologically, confronting the avoided thing.
How to record a dream, why the feeling matters more than the content, and when recurring nightmares are worth a doctor rather than a dictionary — set out once on the main page.
Before you look anything up
How the dream felt matters more than what was in it. The same image can arrive as comfort or as threat, and that difference tells you more than any entry in a dictionary — including this one.
